Resident Factors Associated with Breakthrough SARS-CoV-2 Infections

Objective To examine incidence of and resident characteristics associated with BTIs and severe illness among residents with two mRNA vaccinations. Design Retrospective cohort study Setting and Participants Nursing home (NH) residents who completed their primary series of mRNA COVID-19 vaccination by March 31, 2021. Methods Electronic health records and Minimum Data Set assessments from a multi-state NH data consortium were used to identify BTI and severe illness (a composite measure of hospitalization and/or death within 30 days of BTI) occurring prior to November 24, 2021. A t-test for differences in means was used to compare covariates for residents with and without BTI. Finally, we estimated incidence-rate ratios (IRRs) for BTI with 95% confidence intervals (CI) using a modified Poisson regression approach, comparing residents with BTI vs. residents without. We adjusted for facility-fixed effects in our model. Results Our sample included 23,172 residents from 984 NHs who were at least 14 days past their second mRNA vaccine dose. Of those, 1,173 (5%) developed an incident COVID-19 BTI (mean follow-up time: 250 days). Among residents with BTI, 8.6% were hospitalized or died within 30 days of BTI diagnosis. Factors associated with severe illness included age 85 years and older (IRR=2.08 [95% CI: 1.08-4.02], reference age <65 years), bowel incontinence (IRR=1.73 [95% CI: 1.01-2.99]), coronary artery disease (IRR 1.96 [95% CI: 1.31-2.94]), chronic kidney disease (IRR 1.65 [95% CI: 1.07-2.54]), and schizophrenia (IRR 2.38 [95% CI: 1.19-4.75]). Conclusions and Implications Among vaccinated NH residents, BTIs and associated severe illness are rare. Residents aged 85 years and older and with certain comorbidities appear to be the most vulnerable. Given that the pandemic continues and testing policies have relaxed, this data provides prognostic information for NH facilities faced with continued outbreaks.

Resident Factors Associated With Breakthrough SARS-CoV-2 Infections.

OBJECTIVE: To examine incidence of and resident characteristics associated with breakthrough infections (BTIs) and severe illness among residents with 2 messenger RNA (mRNA) vaccinations. DESIGN: Retrospective cohort study. SETTING AND PARTICIPANTS: Nursing home (NH) residents who completed their primary series of mRNA COVID-19 vaccination by March 31, 2021. METHODS: Electronic health records and Minimum Data Set assessments from a multistate NH data consortium were used to identify BTI and severe illness (a composite measure of hospitalization and/or death within 30 days of BTI) occurring prior to November 24, 2021. A t test for differences in means was used to compare covariates for residents with and without BTI. Finally, we estimated incidence rate ratios (IRRs) for BTI with 95% CIs using a modified Poisson regression approach, comparing residents with BTI vs residents without. We adjusted for facility fixed effects in our model. RESULTS: Our sample included 23,172 residents from 984 NHs who were at least 14 days past their second mRNA vaccine dose. Of those, 1173 (5%) developed an incident COVID-19 BTI (mean follow-up time: 250 days). Among residents with BTI, 8.6% were hospitalized or died within 30 days of BTI diagnosis. Factors associated with severe illness included age ≥85 years (IRR 2.08, 95% CI 1.08-4.02, reference age <65 years), bowel incontinence (IRR 1.73, 95% CI 1.01-2.99), coronary artery disease (IRR 1.96, 95% CI 1.31-2.94), chronic kidney disease (IRR 1.65, 95% CI 1.07-2.54), and schizophrenia (IRR 2.38, 95% CI 1.19-4.75). CONCLUSIONS AND IMPLICATIONS: Among vaccinated NH residents, BTIs and associated severe illness are rare. Residents aged ≥85 years and with certain comorbidities appear to be the most vulnerable. Given that the pandemic continues and testing policies have relaxed, these data provide prognostic information for NH facilities faced with continued outbreaks.

Differences In Nursing Home Staff COVID-19 Testing Rates And Odds Of Vaccination Across Work Shifts.

COVID-19 vaccination and regular testing of nursing home staff have been critical interventions for mitigating COVID-19 outbreaks in US nursing homes. Although implementation of testing has largely been left to nursing home organizations to coordinate, vaccination occurred through a combination of state, federal, and organization efforts. Little research has focused on structural variation in these processes. We examined whether one structural factor, the primary shift worked by staff, was associated with differences in COVID-19 testing rates and odds of vaccination, using staff-level data from a multistate sample of 294 nursing homes. In facility fixed effects analyses, we found that night-shift staff had the lowest testing rates and lowest odds of vaccination, whereas day-shift staff had the highest testing rates and odds of vaccination. These findings highlight the need to coordinate resources and communication evenly across shifts when implementing large-scale processes in nursing homes and other organizations with shift-based workforces.

Association of State COVID-19 Vaccine Mandates With Staff Vaccination Coverage and Staffing Shortages in US Nursing Homes.

Importance: Several states implemented COVID-19 vaccine mandates for nursing home employees, which may have improved vaccine coverage but may have had the unintended consequence of staff departures. Objective: To assess whether state vaccine mandates for US nursing home employees are associated with staff vaccination rates and reported staff shortages. Design Setting and Participants: This cohort study performed event study analyses using National Healthcare Safety Network data from June 6, 2021, through November 14, 2021. Changes in weekly staff vaccination rates and reported staffing shortages were evaluated for nursing homes in states with mandates after the mandate announcement compared with changes in facilities in nonmandate states. An interaction between the mandates and county political leaning was considered. Data analysis was performed from February to March 2022. Exposures: Weeks after announcement of a state's COVID-19 vaccine mandate. Main Outcomes and Measures: Weekly percentage of all health care staff at a nursing home who received at least 1 COVID-19 vaccine dose, and a weekly indicator of whether a nursing home reported a staffing shortage. Results: Among 38 study-eligible states, 26 had no COVID-19 vaccine mandate for nursing home employees, 4 had a mandate with a test-out option, and 8 had a mandate with no test-out option. Ten weeks or more after mandate announcement, nursing homes in states with a mandate and no test-out option experienced a 6.9 percentage point (pp) increase in staff vaccination coverage (95% CI, -0.1 to 13.9); nursing homes in mandate states with a test-out option experienced a 3.1 pp increase (95% CI, 0.5 to 5.7) compared with facilities in nonmandate states. No significant increases were detected in the frequency of reported staffing shortages after a mandate announcement in mandate states with or without test-out options. Increases in vaccination rates in states with mandates were larger in Republican-leaning counties (14.3 pp if no test-out option; 4.3 pp with option), and there was no evidence of increased staffing shortages. Conclusions and Relevance: The findings of this cohort study suggest that state-level vaccine mandates were associated with increased staff vaccination coverage without increases in reported staffing shortages. Vaccination increases were largest when mandates had no test-out option and were also larger in Republican-leaning counties, which had lower mean baseline vaccination rates. These findings support the use of state mandates for booster doses for nursing home employees because they may improve vaccine coverage, even in areas with greater vaccine hesitancy.

COVID-19 Vaccine Uptake Among Nursing Home Staff via Statewide Policy: The Mississippi Vaccinate or Test Out Policy.

Objectives. To examine whether COVID-19 vaccine mandates that allow a test-out exemption for nursing home staff are associated with increased staff vaccination rates in nursing homes. Methods. Using the National Healthcare Safety Network data, we conducted analyses to test trends over time in statewide staff vaccination rates between June 1, 2021, and August 29, 2021, in Mississippi, 4 adjacent states, and the United States overall. Results. COVID-19 staff vaccination rates increased slowly following Mississippi enacting a vaccinate-or-test-out policy, achieving small, but statistically greater gains than most comparator states. Yet, staff vaccination rates in Mississippi remained well below the national average and similar numerically to surrounding states without mandates. Conclusions. Mississippi's COVID-19 vaccinate-or-test policy was ineffective in meaningfully increasing staff vaccination rates. For COVID-19 nursing home mandates to be effective while still balancing the staff turnover risks, facilities might consider a more stringent or hybrid approach (e.g., test-out option not offered to new staff). Public Health Implications. Statewide COVID-19 vaccine mandates, when given a test-out option, do not appear to be an effective strategy to meaningfully increase nursing home staff COVID-19 vaccination.

Factors Affecting SARS-CoV-2 Test Discordance in Skilled Nursing Facilities.

OBJECTIVES: Reverse transcription polymerase chain reaction (PCR) and antigen tests for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are sometimes discordant. We evaluated the discordance between antigen and PCR tests sampled in skilled nursing facilities (SNFs) to assess the relationship of symptom presence, timing between tests, and the presence of a facility outbreak. DESIGN: Observational study using electronic health record data. SETTING AND PARTICIPANTS: Residents of 306 SNFs in 23 states, operated by 1 company. METHODS: We identified all rapid antigen and PCR tests conducted in study SNFs as of January 10, 2021, and classified whether symptoms were present and whether the facility was in outbreak at time of testing. We calculated the proportions of antigen tests with discordant follow-up PCR results conducted no more than 2 days after the antigen test. RESULTS: Of the 171,280 antigen tests in 34,437 SNF residents, 20,991 (12.3%) were followed by a PCR test within 2 days. A total of 1324 negative antigen tests were followed by a positive PCR result, representing 0.8% of all antigen tests and 6.3% of repeated antigen tests; while 337 positive antigen tests were followed by a negative PCR result, representing 0.2% of all antigen tests and 1.6% of repeated antigen tests. Discordance more often occurred when residents were symptomatic at time of antigen testing, during known facility outbreaks, and when the antigen test was compared with a PCR test done within 2 days vs 1 day. CONCLUSIONS AND IMPLICATIONS: Overall, discordance between SARS-CoV-2 antigen and PCR tests was low. Discordance was more common when the individual was symptomatic at time of antigen testing and during facility outbreaks. This suggests that a testing strategy which couples widespread use of antigen tests with clinical thresholds to conduct follow-up confirmatory PCR testing appears to perform well in SNFs, where timely and accurate SARS-CoV-2 case identification are critical.

COVID-19 vaccine booster dose needed to achieve Omicron-specific neutralisation in nursing home residents.

BACKGROUND: Nursing home (NH) residents have borne a disproportionate share of SARS-CoV-2 morbidity and mortality. Vaccines have limited hospitalisation and death from earlier variants in this vulnerable population. With the rise of Omicron and future variants, it is vital to sustain and broaden vaccine-induced protection. We examined the effect of boosting with BNT162b2 mRNA vaccine on humoral immunity and Omicron-specific neutralising activity among NH residents and healthcare workers (HCWs). METHODS: We longitudinally enrolled 85 NH residents (median age 77) and 48 HCWs (median age 51), and sampled them after the initial vaccination series; and just before and 2 weeks after booster vaccination. Anti-spike, anti-receptor binding domain (RBD) and neutralisation titres to the original Wuhan strain and neutralisation to the Omicron strain were obtained. FINDINGS: Booster vaccination significantly increased vaccine-specific anti-spike, anti-RBD, and neutralisation levels above the pre-booster levels in NH residents and HCWs, both in those with and without prior SARS-CoV-2 infection. Omicron-specific neutralisation activity was low after the initial 2 dose series with only 28% of NH residents' and 28% HCWs' titres above the assay's lower limit of detection. Omicron neutralising activity following the booster lifted 86% of NH residents and 93% of HCWs to the detectable range. INTERPRETATION: With boosting, the vast majority of HCWs and NH residents developed detectable Omicron-specific neutralising activity. These data provide immunologic evidence that strongly supports booster vaccination to broaden neutralising activity and counter waning immunity in the hope it will better protect this vulnerable, high-risk population against the Omicron variant.

Addressing hesitancy to COVID-19 vaccines in healthcare assistants.

COVID-19 vaccination rates have been suboptimal in frontline healthcare assistants (HCAs). We sought to characterize contributors to COVID-19 vaccine hesitancy among HCAs. We conducted an analysis of online survey responses from members of the National Association of Health Care Assistants from December 2020-January 2021. Respondents were asked what it would take for them to be vaccinated against COVID-19. Responses from 309 HCAs were coded to characterize respondents' willingness to be vaccinated and identify contributors to vaccine hesitancy. Approximately 60% (n = 185) of HCAs expressed hesitancy but would consider getting vaccinated under certain circumstances. We identified 8 overarching themes for contributors to COVID-19 vaccine hesitancy, the most common being safety concerns (70% of respondents). Others included efficacy (11.4%), workplace requirements (9.7%), societal influence (9.2%), and compensation (8.1%). Interventions to increase vaccine uptake among HCAs may be most effective by addressing concerns regarding the short-term and long-term safety implications of COVID-19 vaccines.

Significant Reduction in Vaccine-Induced Antibody Levels and Neutralization Activity Among Healthcare Workers and Nursing Home Residents 6 Months Following Coronavirus Disease 2019 BNT162b2 mRNA Vaccination.

Antibody decline occurred from 2 weeks to 6 months post-BNT162b2 mRNA vaccination in nursing home (NH) residents and healthcare workers. Antispike, receptor-binding domain, and neutralization levels dropped >81% irrespective of prior infection. Notably, 69% of infection-naive NH residents had neutralizing antibodies at or below the assay's limit of detection.

Evaluating the Findings of the IMPACT-C Randomized Clinical Trial to Improve COVID-19 Vaccine Coverage in Skilled Nursing Facilities.

IMPORTANCE: Identifying successful strategies to increase COVID-19 vaccination among skilled nursing facility (SNF) residents and staff is integral to preventing future outbreaks in a continually overwhelmed system. OBJECTIVE: To determine whether a multicomponent vaccine campaign would increase vaccine rates among SNF residents and staff. DESIGN, SETTING, AND PARTICIPANTS: This was a cluster randomized trial with a rapid timeline (December 2020-March 2021) coinciding with the Pharmacy Partnership Program (PPP). It included 133 SNFs in 4 health care systems across 16 states: 63 and 70 facilities in the intervention and control arms, respectively, and participants included 7496 long-stay residents (>100 days) and 17 963 staff. INTERVENTIONS: Multicomponent interventions were introduced at the facility level that included: (1) educational material and electronic messaging for staff; (2) town hall meetings with frontline staff (nurses, nurse aides, dietary, housekeeping); (3) messaging from community leaders; (4) gifts (eg, T-shirts) with socially concerned messaging; (5) use of a specialist to facilitate consent with residents' proxies; and (6) funds for additional COVID-19 testing of staff/residents. MAIN OUTCOMES AND MEASURES: The primary outcomes of this study were the proportion of residents (from electronic medical records) and staff (from facility logs) who received a COVID-19 vaccine (any), examined as 2 separate outcomes. Mixed-effects generalized linear models with a binomial distribution were used to compare outcomes between arms, using intent-to-treat approach. Race was examined as an effect modifier in the resident outcome model. RESULTS: Most facilities were for-profit (95; 71.4%), and 1973 (26.3%) of residents were Black. Among residents, 82.5% (95% CI, 81.2%-83.7%) were vaccinated in the intervention arm, compared with 79.8% (95% CI, 78.5%-81.0%) in the usual care arm (marginal difference 0.8%; 95% CI, -1.9% to 3.7%). Among staff, 49.5% (95% CI, 48.4%-50.6%) were vaccinated in the intervention arm, compared with 47.9% (95% CI, 46.9%-48.9%) in usual care arm (marginal difference: -0.4%; 95% CI, -4.2% to 3.1%). There was no association of race with the outcome among residents. CONCLUSIONS AND RELEVANCE: A multicomponent vaccine campaign did not have a significant effect on vaccination rates among SNF residents or staff. Among residents, vaccination rates were high. However, half the staff remained unvaccinated despite these efforts. Vaccination campaigns to target SNF staff will likely need to use additional approaches. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04732819.

Reduced BNT162b2 Messenger RNA Vaccine Response in Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2)-Naive Nursing Home Residents.

After BNT162b2 messenger RNA vaccination, antibody levels to spike, receptor-binding domain, and virus neutralization were examined in 149 nursing home residents and 110 healthcare worker controls. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-naive nursing home residents' median post-second vaccine dose antibody neutralization titers are one-quarter that of SARS-CoV-2-naive healthcare workers.

Does a lack of vaccine side effects correlate with reduced BNT162b2 mRNA vaccine response among healthcare workers and nursing home residents?

BACKGROUND: The BNT162b2 SARS-CoV-2 mRNA vaccination has mitigated the burden of COVID-19 among residents of long-term care facilities considerably, despite being excluded from the vaccine trials. Data on reactogenicity (vaccine side effects) in this population are limited. AIMS: To assess reactogenicity among nursing home (NH) residents. To provide a plausible proxy for predicting vaccine response among this population. METHODS: We enrolled and sampled NH residents and community-dwelling healthcare workers who received the BNT162b2 mRNA vaccine, to assess local or systemic reactogenicity and antibody levels (immunogenicity). RESULTS: NH residents reported reactions at a much lower frequency and lesser severity than the community-dwelling healthcare workers. These reactions were mild and transient with all subjects experiencing more local than systemic reactions. Based on our reactogenicity and immunogenicity data, we developed a linear regression model predicting log-transformed anti-spike, anti-receptor-binding domain (RBD), and neutralizing titers, with a dichotomous variable indicating the presence or absence of reported reactions which revealed a statistically significant effect, with estimated shifts in log-transformed titers ranging from 0.32 to 0.37 (all p < 0.01) indicating greater immunogenicity in subjects with one or more reported reactions of varying severity. DISCUSSION: With a significantly lower incidence of post-vaccination reactions among NH residents as reported in this study, the BNT162b2 mRNA vaccine appears to be well-tolerated among this vulnerable population. If validated in larger populations, absence of reactogenicity could help guide clinicians in prioritizing vaccine boosters. CONCLUSIONS: Reactogenicity is significantly mild among nursing home residents and overall, subjects who reported post-vaccination reactions developed higher antibody titers.

Strategies associated with COVID-19 vaccine coverage among nursing home staff.

BACKGROUND: After the first of three COVID-19 vaccination clinics in U.S. nursing homes (NHs), the median vaccination coverage of staff was 37.5%, indicating the need to identify strategies to increase staff coverage. We aimed at comparing the facility-level activities, policies, incentives, and communication methods associated with higher staff COVID-19 vaccination coverage. METHODS: Design. Case-control analysis. SETTING: Nationally stratified random sample of 1338 U.S. NHs participating in the Pharmacy Partnership for Long-Term Care Program. PARTICIPANTS: Nursing home leadership. MEASUREMENT: During February 4-March 2, 2021, we surveyed NHs with low (<35%), medium (40%-60%), and high (>75%) staff vaccination coverage, to collect information on facility strategies used to encourage staff vaccination. Cases were respondents with medium and high vaccination coverage, whereas controls were respondents with low coverage. We used logistic regression modeling, adjusted for county and NH characteristics, to identify strategies associated with facility-level vaccination coverage. RESULTS: We obtained responses from 413 of 1338 NHs (30.9%). Compared with facilities with lower staff vaccination coverage, facilities with medium or high coverage were more likely to have designated frontline staff champions (medium: adjusted odds ratio [aOR] 3.6, 95% CI 1.3-10.3; high: aOR 2.9, 95% CI 1.1-7.7) and set vaccination goals (medium: aOR 2.4, 95% 1.0-5.5; high: aOR 3.7, 95% CI 1.6-8.3). NHs with high vaccination coverage were more likely to have given vaccinated staff rewards such as T-shirts compared with NHs with low coverage (aOR 3.8, 95% CI 1.3-11.0). Use of multiple strategies was associated with greater likelihood of facilities having medium or high vaccination coverage: For example, facilities that used ≥9 strategies were three times more likely to have high staff vaccination coverage than facilities using <6 strategies (aOR 3.3, 95% CI 1.2-8.9). CONCLUSIONS: Use of designated champions, setting targets, and use of non-monetary awards were associated with high NH staff COVID-19 vaccination coverage.

Perceptions of COVID-19 vaccines among healthcare assistants: A national survey.

BACKGROUND: Limited COVID-19 vaccination acceptance among healthcare assistants (HCAs) may adversely impact older adults, who are at increased risk for severe COVID-19 infections. Our study objective was to evaluate the perceptions of COVID-19 vaccine safety and efficacy in a sample of frontline HCAs, overall and by race and ethnicity. METHODS: An online survey was conducted from December 2020 to January 2021 through national e-mail listserv and private Facebook page for the National Association of Health Care Assistants. Responses from 155 HCAs, including certified nursing assistants, home health aides, certified medical assistants, and certified medication technicians, were included. A 27-item survey asked questions about experiences and perceptions of COVID-19 vaccines, including how confident they were that COVID-19 vaccines are safe, effective, and adequately tested in people of color. Multivariable regression was used to identify associations with confidence in COVID-19 vaccines. RESULTS: We analyzed data from 155 completed responses. Among respondents, 23.9% were black and 8.4% Latino/a. Most respondents worked in the nursing home setting (53.5%), followed by hospitals (12.9%), assisted living (11.6%), and home care (10.3%). Respondents expressed low levels of confidence in COVID-19 vaccines, with fewer than 40% expressing at least moderate confidence in safety (38.1%), effectiveness (31.0%), or adequate testing in people of color (27.1%). Non-white respondents reported lower levels of confidence in adequate testing of vaccines compared to white respondents. In bivariate and adjusted models, respondents who gave more favorable scores of organizational leadership at their workplace expressed greater confidence in COVID-19 vaccines. CONCLUSION: Frontline HCAs reported low confidence in COVID-19 vaccines. Stronger organizational leadership in the workplace appears to be an important factor in influencing HCA's willingness to be vaccinated. Action is needed to enhance COVID-19 vaccine uptake in this important population with employers playing an important role to build vaccine confidence and trust among employees.

Lessons learned from frontline skilled nursing facility staff regarding COVID-19 vaccine hesitancy.

BACKGROUND: Presently a median of 37.5% of the U.S. skilled nursing facility (SNF) workforce has been vaccinated for COVID-19. It is essential to understand vaccine hesitancy among SNF workers to inform vaccine campaigns going forward. OBJECTIVE: To describe the concerns raised among healthcare workers and staff from SNFs during town hall meetings. DESIGN: Sixty-three SNFs from four corporations were invited to send Opinion Leaders, outspoken staff from nursing, nurse aid, dietary, housekeeping or recreational therapy, to attend a 1-h virtual town hall meeting. Meetings used a similar format where the moderator solicited concerns that the attendees themselves had or had heard from others in the facility about the COVID-19 vaccine. Physicians and moderators used personal stories to address concerns and reaffirmed positive emotions. SETTING: Twenty-six video town hall meetings with SNF staff. PARTICIPANTS: Healthcare workers and staff, with physicians serving as content experts. MEASUREMENT: Questions and comments about the COVID-19 vaccines noted by physicians. RESULTS: One hundred and ninety three staff from 50 facilities participated in 26 meetings between December 30, 2020 and January 15, 2021. Most staff reported getting information about the vaccine from friends or social media. Concerns about how rapidly the vaccines were developed and side effects, including infertility or pregnancy related concerns, were frequently raised. There were no differences in concerns raised by discipline. Questions about returning to prior activities after being vaccinated were common and offered the opportunity to build on positive emotions to reduce vaccine hesitancy. CONCLUSIONS: Misinformation about the COVID-19 vaccine was widespread among SNF staff. Sharing positive emotions and stories may be more effective than sharing data when attempting to reduce vaccine hesitancy in SNF staff.

A multi-center trial of exercise and testosterone therapy in women after hip fracture: Design, methods and impact of the COVID-19 pandemic.

BACKGROUND: Up to 75% of hip fracture patients never recover to their pre-fracture functional status. Supervised exercise that includes strength training can improve functional recovery after hip fracture. The role of testosterone replacement for augmenting the effects of exercise in older women after hip fracture is unknown. METHODS: The Starting Testosterone and Exercise after Hip Injury (STEP-HI) Study is a 6-month Phase 3 multicenter randomized placebo-controlled trial designed to compare supervised exercise (EX) plus 1% testosterone topical gel, with EX plus placebo gel, and with enhanced usual care (EUC). Female hip fracture patients age ≥ 65 years are being recruited from clinical centers across the United States. Participants are community dwelling and enrolled within 24 weeks after surgical repair of the fracture. The EX intervention is a center-based program of progressive resistance training. The EUC group receives a home exercise program and health education. Participants receive dietary counseling, calcium and vitamin D. The primary outcome is the Six Minute Walk Distance. Secondary outcomes include physical performance measures, self-reported function and quality of life, and dual energy x-ray absorptiometry measures of body composition and bone mineral density. RESULTS: Enrollment, interventions, and follow-up are ongoing. We describe the impact of the coronavirus disease 2019 pandemic on the trial, including modifications made to allow continuation of the interventions and outcome data collection using remote video and audio technology. CONCLUSIONS: Results from the STEP-HI study are expected to have important clinical and public health implications for management of the growing population of hip fracture patients.

An advance care planning long-term care initiative in response to COVID-19.

OBJECTIVE: Describe a systematic approach to address advance care planning (ACP) during a COVID-19 outbreak and its impact on the incidence of new do-not-hospitalize (DNH) directives among long-term care (LTC) residents. DESIGN: Prospective quality improvement initiative. SETTING: Two long-term chronic care campuses within a large academic healthcare organization. PARTICIPANTS: LTC residents with activated healthcare proxies who lacked DNH directives based on documentation in the electronic medical record (EMR) as of April 13, 2020. INTERVENTION: Using a structured discussion guide, trained healthcare staff from various disciplines contacted the residents' proxies to conduct COVID-19 focused ACP discussions. Residents without DNH directives with COVID-19 were prioritized. Preferences ascertained in the discussion were communicated to the residents' primary care teams and directives were updated in the EMR accordingly. MEASUREMENTS: Residents who acquired a new DNH directive during the study initiative were determined using the EMR. Subsequent changes in DNH orders, hospitalizations, and deaths were ascertained by retrospective chart review from the date of new DNH through August 5, 2020. RESULTS: At baseline, 315/581 (54%) of LTC residents did not have a DNH directive. Their mean age was 87 (±9) years and 70% were female. Following ACP discussions, 124/315 (39%) of residents acquired a new DNH directive. Among residents with new DNH directives, 65/124 (52%) were diagnosed with COVID-19 from April 2, 2020 to May 21, 2020. During follow-up, only 6/124 (4.8%) residents had their DNH order reversed, 2/124 (1.6%) residents were hospitalized with illnesses unrelated to COVID-19, and 29/124 (23%) died. CONCLUSIONS: There was substantial opportunity to increase the proportion of LTC residents with DNH orders during the COVID-19 pandemic through a systematic ACP initiative which utilized real-time EMR data. New directives to avoid hospitalizations were sustained among the majority of residents beyond the peak of the pandemic.

Risk Factors, Presentation, and Course of Coronavirus Disease 2019 in a Large, Academic Long-Term Care Facility.

OBJECTIVE: To describe clinical characteristics and risk factors associated with coronavirus disease 2019 (COVID-19) in long-stay nursing home residents. DESIGN AND PARTICIPANTS: Retrospective cohort study (March 16, 2020 to May 8, 2020). SETTING: Academic long-term chronic care facility (Boston, MA). PARTICIPANTS: Long-term care residents. METHODS: Patient characteristics and clinical symptoms were obtained via electronic medical records and Minimum Data Set. Staff residence was inferred by zip codes. COVID-19 infection was confirmed by polymerase chain reaction testing using nasopharyngeal swabs. Residents were followed until discharge from facility, death, or up to 21 days. Risks of COVID-19 infection were modeled by generalized estimating equation to estimate the relative risk (RR) and 95% confidence intervals (CI) of patient characteristics and staff community of residence. RESULTS: Overall 146 of 389 (37.5%) long-stay residents tested positive for COVID-19. At the time of positive test, 66 of 146 (45.5%) residents were asymptomatic. In the subsequent illness course, the most common symptom was anorexia (70.8%), followed by delirium (57.6%). During follow-up, 44 (30.1%) of residents with COVID-19 died. Mortality increased with frailty (16.7% in pre-frail, 22.2% in moderately frail, and 50.0% in frail; P < .001). The proportion of residents infected with COVID-19 varied across the long-term care units (range: 0%‒90.5%). In adjusted models, male sex (RR 1.80, 95% CI 1.07, 3.05), bowel incontinence (RR 1.97, 95% CI 1.10, 3.52), and staff residence remained significant predictors of COVID-19. For every 10% increase in the proportion of staff living in a high prevalence community, the risk of testing positive increased by 6% (95% CI 1.04, 1.08). CONCLUSIONS AND IMPLICATIONS: Among long-term care residents diagnosed with COVID-19, nearly one-half were asymptomatic at the time of diagnosis. Predictors of COVID-19 infection included male sex, bowel incontinence, and staff residence in a community with a high burden of COVID-19. Universal testing of patients and staff in communities with high COVID-19 rates is essential to mitigate outbreaks.
